ASUS RT-AC5300 help in diagnosis


New Around Here
Hello everyone
Hello everyone
I have an Asus RT-AC5300 router that has started to malfunction. Namely, after starting, the Power LED lights up.
Once I was able to upload a new firmware.
It is currently in a loop and is resetting.
Any hel needed.
Below is a listing from the serial port:
